Engineering Datasheet: THM Coin Cell Retainer, Direct Footprint Replacement for Keystone 3031
Securing micro coin cells in high-vibration environments requires robust through-hole integration. The Jiatel JT-BC-1025-KS3031 is a direct footprint replacement for the Keystone 3031. Unlike the SMT 3030 variant, this retainer deploys a dual-pin THM architecture. It provides extreme resistance against lateral shear forces. You can execute seamless board-level integration for CR927 and CR1025 cells. You do not need to alter existing PCB drill hole coordinates.
Verified Board-Level Parameters
| Target Cross-Reference | Direct Footprint Replacement for Keystone 3031 |
| Mounting Architecture | Through-Hole Mount (THM) Dual Pin |
| Axial Pin Pitch | 10.62mm Spread (Requires 2-Ø1.80mm Drills) |
| Negative Pad Constraint | 4.00mm Square Minimum (Center Pad) |
| Base Metallurgy | T=0.15mm Phosphor Bronze | Nickel Plated |
Target Deployments
- Industrial Controllers: Heavy-duty PLC modules requiring wave-soldered RTC backup.
- Medical Equipment: Stationary diagnostic hardware demanding maximum terminal retention.
- IoT Infrastructure: Outdoor sensor nodes exposed to environmental shock.
Metallurgical Rigidity & Wave Soldering Integrity
We stamp the JT-BC-1025-KS3031 from rigid T=0.15mm Phosphor Bronze. The top clamping arms maintain continuous pressure on the CR927/CR1025 cells, preventing voltage drop during mechanical impact. We finish the THM tails with high-density Nickel Plating. This maximizes wave solder wettability across the 10.62mm pin layout. It eliminates the risk of cold solder joints and physical detachment.
NPI PCB Footprint Audit & SLA Directive
Through-hole integration demands strict adherence to pin pitch dimensions and drill tolerances. Layout errors cause pin bending and wave soldering failures. Our engineering rules strictly prohibit the distribution of unverified digital mockups. We execute structural footprint validation exclusively through official [Technical Datasheets]. We rely on dimensionally controlled [2D Footprint Specs].
Confirm that our THM retainer matches your FR4 drill pattern. We must deploy our Senior NPI Engineering Team to ensure a 1:1 footprint replacement. Submit your board constraints directly to our technical desk: NPI Engineering Queue. We will dispatch matched, production-ready PDF drawings within 12 working hours.
